Thematically I think the Navigator works for my character more than swordsman, but I'm hesitant not knowing the combat system or the potential loss of survivability if I give it up. If it's mostly flavor, then I'd say let's switch it.
Also, I am going to be away for vacation a bit in December - I'm around this week and next but then I'm off for a week. I expect you're going to want to start and I don't want to surprise anyone with an absence of a week right off the bat.
I'll be on leave around Christmas, so I won't be surprised if this game slows down until the vacationing is done.
You need a combat specialization unless you're a mage or cleric. The specific combat specializations are for those characters melee-inclined, and it makes those characters specialists specifically in those weapons and no others. I set it up this way so we don't have those Mary Sues who are like: I specialize in all weapons and magic, all specializations, and I speak and understand every language. I am a Mary Sue slayer.
